Answer:
x = -3
x = 7
Step-by-step explanation:
If either term is zero the product is zero
(2x + 6)(x - 7) = 0
2x + 6 = 0
2x = -6
x = -3
x - 7 = 0
x = 7
This is a problem of Difference-of-squares. We know that for a difference of squares

the factorization is given by:

To learn this you need to remember that a <em>difference</em> means <em>subtraction.</em> So applying those concepts we can solve this problem step by step.
Applying distributive property:

Applying distributive property again:

Simplifying:
<em>The correct answer is C</em>
Answer:
Step-by-step explanation:
The key and the most critical step is to draw the line first. Don't do anything else before that.
(2,-8) (-2,-8)
What you find out is that the y value is always - 8.
So the line has no slope and any x value
y = 0*x + b
y = - 8 is the equation of the line.
Y int at (0,4).....thru points (4,1)
slope = (1 - 4) / (4 - 0) = -3/4
initial value 4, slope(rate of change) is -3/4 <==
=======================
y = 22,000x + 40,000
=======================
y = 12x + 48
slope(rate of change) = 12
=======================
(1,10)(2,8)
slope = (8-10) / (2-1) = -2/1 = -2
y = mx + b
8 = -2(2) + b
8 = -4 + b
8 + 4 = b
12 = b
slope(rate of change) = -2
initial value = 12
I am not getting any of ur answer choices ...
======================
y = x + 6
initial value = 6
<span>(-4-x)-(3y-9x)
= </span><span>-4 - x - 3y + 9x
= 8x - 3y - 4</span>
